Results for SpO2 (a), mTOI (b), mOxyHb (c), mDeOxyHb (d), mTotHb (e) at rest and at the end of the 3-min step-test (exercise). Values demonstrate the median, iqr, min, max values. Dots indicate the individual values of each participant. ⫪ p<0.001 main difference between environments, * p<0.001 to NN, # p = 0.008 to NH.
